The general arrangement ot feeding and delivery mechanisms, the beds and cylinders, and web-guides, except the peculiar looping devices, are substantially similar to those ordinarily employed in the duplex tlat-bed webpre'sses, and the mechanisms as an entirety operate substantially as describedin Coxs patent, No. 478,503, of July 2, 1892.- As the upper looping-rollers are mounted on same supports as the lower looping-rollers and have the same extent o'l movement, it lollows*that the three upper' loops of the web will exactly coincide with the three lower loops of the web, and as such lower loops are forming the'upper loops give out exactly the same quantity of web that is taken up. by the lower loops, andlias the lower loops give the web out the upper loops take up all the web given out by the lower loops.

ln the example shown three movable looping-rollers are employed in each set, which reduces the extent of movement of the looping1' ller's necessary to take up the desired quantity of web and lessens the speed of movement of' thrframe, consequently reducing the eccentricity and easing; the cams. l do not, however, restrict myself to the arrangement ot looping-rollers in a substantially vertical position. i

The advantages of the improved construe tions are the easing,r up of the cams andthe slowing,r and lesseningr of movement of the looping-rollers.

l do not wish to restrict myself to any precise plural number ol" looping-rollers, nor do I restrict myself to the particular mechanism shown for operating these -loopin Ag-rollers, as it is only essential that the looping-in and looping-out rollers have such relation to each other that the movement ol web taken by one will exactly correspond to the movement of web given oli by the other.

Hav-ing thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

l. ln combination, web feeding and delivery devices, and two sets ol' movable weblcoping' devices andan oszcillatilngT support therclor, each set comprising' a plurality of loopersl movingr oppositely to the otherwsaid sets' beingr mounted on opposite sides of the fulcrum ol the support, and one set ol looping devices acting,- to lorm loops in the web while thc other set ol' devices is giving out loops.

2. In combination an oscillating support, two sets of web-looping devices mounted on said support respectively at opposite sides of its iulcrum, each set comprising a series of parallel rollers successively nearer the fulcrum of the support.

3. ln combination with an oscillating support, sets ol welwlooping devices mounted on said support at opposite sides of its iulcrum, each set of devices comprising a plurality of parallel loopers adapted to simultaneously form loops in the web or to simultaneously give out such loops, adjacent sets of relatively liXed rollers opposite the sets oll movable loopers, and means for oscillating` said support.

4, In a web-printing machine, the combination of web feeding and delivering' devices, and web-printing mechanism intermediate the feed and delivery comprising' stationary beds and coat-ting cylinders; with a vertically-disposed oscillating support located between the feeding and delivery devices and the printing' mechanism, a plurality of weblooping devices mounted on one end of said support between the feed and printing' mechanisms, a pliu'ality oli web-looping' devices mountedpn the opposite end of said support between the printing and delivery mechanisms, and n plurality ol stationary web-guides coopcratine, witn said looping devices, substantially as described.

5. -ln a web-printing machine, the combination ol' web feeding,f and delivering devices, and.web-printing mechanism intermediate the Yl'eed and delivery; with a pair ot oscillating supports between the feeding and delivering devices and the printing mechanism, a plurality of web-looping devices mounted on one end ol` said supports between thefeed and printing mechanisms; an adjacent set of stationary web-guidcs 'coacting with said loopers; a plurality of web-looping devie s mounted on thc opposite end ot said supports between the printing' and delivery mechane isms, and an adjacent set of stationary web-guides enacting lwith said loopers; each set oi' movable loopers being' adapted to simultaneously form or give out loops in the web, and one set of movable loopingl devices operating' oppositely to the other, all substantially as described. z
